The physical store is not the "means of production" in urban areas, but a closer analog is the piece of paper that allows a given square foot of floorspace (for any use) the right to exist within the city for a given period of time. You could call this piece of paper a floorspace factory, since it's the limiting factor. Somehow we have decided it's best to have as few floorspace factories as possible.
Land (or in modern terms, location value) has been seen as a means of production along with labor and capital since Adam Smith.
Yes, but back then you could build largely what you wanted to on the land. Now you can’t. The pieces of paper are more limiting than the actual land.
